摘要:
A low-sulfur, low-phosphorus composition comprising an oil of lubricating viscosity; a substantially nitrogen-free sufurized olefin antiwear agent; a nitrogen-containing dispersant; and an overbased detergent selected from the group consisting of salixarates, saligenins, salicylates, and glyoxylates; containing less than about 0.1 percent by weight phosphorus, less than about 0.5 percent by weight sulfur, and having less than about 1.2% sulfated ash, is useful for lubricating a diesel engine, exhibiting good antiwear performance.
摘要:
A lubricant and concentrate composition comprises a hindered-phenol-containing diester antioxidant derived from a hydrocarbyl diol or an amide diol. A method for improving the performance of a lubricant composition, especially a lubricant composition for an internal combustion engine, comprises the antioxidant.
摘要:
A lubricating composition comprising an oil of lubricating viscosity, 1 to 1000 parts per million by weight of titanium in the form of an oil-soluble titanium-containing material, and at least one additional lubricant additive provides beneficial effects on properties such as deposit control, oxidation, and filterability in engine oils.
摘要:
A dispersant composition comprising the product of an amine, an alcohol, or an amino alcohol, with a hydrocarbyl-substituted succinic anhydride component exhibits improved viscosity stability and reduced chlorine content, when the hydrocarbyl-substituted succinic anhydride component comprises: (a) 10 to 95 weight percent of a component prepared by reacting a polyisobutylene with maleic anhydride in the presence of chlorine; and (b) 5 to 90 weight percent of a component prepared by reacting a polyisobutylene with maleic anhydride in the substantial absence of chlorine.

Organo-Cobalt complexes having long chain saturated and unsaturated alkyl functionality as multifunctional additives in crankcase oils and the method of preparation thereof.
摘要:
Compositions for improving plant health, the compositions comprising at least one water-soluble pesticide and at least one non-herbicidal water-insoluble agrochemical, are described. Also described are processes for preparing the compositions and methods of improving agronomic crop plant health using the compositions.
摘要:
Hypersulfated disaccharides of formula I and other hypersulfated disaccharides disclosed herein are used to treat diseases or conditions associated with human neutrophil elastase imbalances. The disaccharides and/or intermediates useful to prepare such compounds are prepared from heparin. The diseases and conditions which are treated with a compound of formula I include chronic obstructive pulmonary disorder (COPD) and cystic fibrosis (CF). The formulations are delivered to the lungs in an aerosol formulation or dry powder means or via nebulization. Oral forms are also suitable.
摘要:
Lubricant compositions of (a) an oil of lubricating viscosity; (b) a molybdenum salt; (c) a monoester of (i) a polyol and (ii) an aliphatic carboxylic acid containing about 12 to about 24 carbon atoms; and (d) a borate ester of a vicinal diol containing 12 to 24 carbon atoms provide good fuel economy and power output to internal combustion engines.
摘要:
Disclosed are compounds that are derivatives of brevetoxin, or PbTx, pharmaceutical formulations comprising the compounds, and methods of regulating mucus transport in a cell, treating mucociliary dysfunction and diseases related to decreased mucus transport, wherein the compounds are of the Formula (I), and Formula (III): wherein R, R1, R2, R3, A, n, and Y are as defined herein for each compound.
摘要:
The present invention relates to stable glyphosate formulations with improved efficacy by a highly effective alkoxylated alkylamine quaternary surfactant at a very low used level. The alkoxylated alkylamine quaternary surfactant is compatible in all salts of glyphosate formulations (including potassium and ammonium) EVEN AT VERY HIGH CONCENTRATION (470-600 g a.e./l).
